HA12211NT
Audio Signal Processor for Cassette Deck (Deck 1 Chip)

ADE-207-223A (Z) 2nd. Edition June 1997 Description
HA12211NT is silicon monolithic bipolar IC providing REC equalizer system, PB equalizer system and each electronic control switch in one chip.

Functions
PB equalizer 2 channel REC equalizer 2 channel Each electronical control switch to change equalizer characteristics REC mute REC head return switch

Features
REC equalizer is very small number of external parts.(4 types of frequency characteristics built-in) PB equalizer built-in. (A/B input changing system, 4 types of frequency characteristics) Independent PB sensitivity for A deck, B deck. Normal-speed/high-speed, normal tape/chrome tape switching built-in. Controllable from direct micro-computer output. Available to reduce substrate-area because of high integration and small external parts.
